OPTICAL HEAD DEVICE FOR PROCESSING A WORK PIECE USING A LASER, CAPABLE OF EXPANDING A WORK SPACE OF A MACHINE TOOL

摘要

PURPOSE: An optical head device for processing a work piece using a laser is provided to measure the temperature of the work piece in real time, and to locate various sensors and cables in the inside of the device.;CONSTITUTION: An optical head device for processing a work piece using a laser comprises a body(10), an optical fiber(31), a beam shaping lens set unit, a first beam splitter, a first total reflection mirror, a focal distance adjustment lens unit, and a rotating unit(20). The rotating unit receives the first beam splitter and the first total reflection mirror. A condenser lens is installed on one side of the rotating unit. The rotating unit rotates the first beam splitter and the first total reflection mirror while maintaining the same perpendicular line.;COPYRIGHT KIPO 2010
